.NET 5 and .NET 6 public client applications

If you have a Windows application which targets net5.0, net5.0-windows, net5.0-windowsX, net6.0, or net6.0-windows and would like to use either WAM or embedded browser, you must change the app target to at least net6.0-windows10.0.17763.0. System browser works on all of the above targets.
The recommendation is to use new Windows broker preview, as it offers better experience than current WAM implementation and will be generally available in the near future. If you want to try the new broker preview, install the NuGet package Microsoft.Identity.Client.Broker and call the .WithBrokerPreview() method. For details, see https://aka.ms/msal-net-wam.
